Ten months of work, in heat and in cold
Your new system will run ten months out of the year here. Cooling season runs April through October, seven months, with summer afternoons that average 105°F. Heating season is shorter, December through February, but winter nights still average 43°F.
Most homes here heat with electricity, so the same system carries both jobs almost all year. Whatever you install has to hold up to that kind of run time, not just a mild afternoon now and then. The contractor sizing your equipment should size it for the long cooling season and the short cold one, not just whichever feels more urgent today.

Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors tests and licenses HVAC contractors before they can legally take on a job like this. That license belongs to the contractor, not to any one installation, so it does not expire or need renewal for each new job. It tells you the contractor was tested and is on record with the state.
For an installation, that license is what stands behind the person doing the work, but Yuma County and its cities still have their own say. In most places here, putting in a new furnace, air conditioner or heat pump requires a permit from the local building office, and the finished work gets an inspection. That inspection is separate from the state license. It checks that the equipment was installed correctly and safely, not who installed it.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or when it can't keep up anymore, whichever comes first. If your air conditioner is struggling to hold the house cool through the summer afternoons here, or your furnace is short cycling on the cold nights from December through February, that's a sign the equipment is wearing out rather than just having a bad day. A unit that needs frequent repairs, or one where a single repair is a large share of what a new system would cost, is usually past the point of being worth fixing. Age matters too. Most central air conditioners and furnaces are built to last a couple of decades, and once you're near that mark, a breakdown in the middle of summer is a real risk, not a hypothetical one.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's usually worth doing together. A furnace and air conditioner installed at the same time are matched to work as one system, and pairing an aging furnace with a new air conditioner, or the other way around, can mean the newer unit never runs the way it was designed to. Homes here need cooling seven months a year and heat only three, so the air conditioner does most of the work and tends to wear out first. But if your furnace still has plenty of life left, there's no reason to replace it just because the air conditioner failed. A contractor can look at the age and condition of each and tell you honestly whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- The contractor starts by sizing the system for your house, since a unit that's too big or too small won't heat or cool it properly no matter how well it's installed. The old equipment comes out, and the new furnace or air conditioner goes in along with any changes needed to the ductwork, refrigerant lines, or electrical connections. Once it's in place, the contractor tests it, checks refrigerant charge and airflow, and confirms the thermostat and controls are working correctly. In Arizona, the contractor doing this work has to hold a state license through the Registrar of Contractors, so it's worth confirming that before work starts. A contractor can walk you through what your specific installation will involve.
